Commands for Configuring Slots and Ports on a Switch
All traffic egressing the monitor port is tagged on the BlackDiamond 8800 family of switches and the
Summit X450 switch. Even if some untagged ports send mirrored traffic to the monitor port, that traffic
also egresses the monitor port tagged with the internal VLAN ID.
NOTE
On the BlackDiamond 8800 family of switches and the Summit X450 switch, mirroring and sFlow are mutually
exclusive; you can enable either sFlow or mirroring but not both.
BlackDiamond 10K switch only. The traffic filter can be defined based on one of the following criteria:
Physical port—All data that traverses the port, regardless of VLAN configuration, is copied to the
●
monitor port.
VLAN—All data to and from a particular VLAN, regardless of the physical port configuration, is
●
copied to the monitor port.
Virtual port—All data specific to a VLAN on a specific port is copied to the monitor port.
●
NOTE
Beginning with ExtremeWare XOS 11.0, the monitor port must be explicitly configured for tagged or untagged.
Mirroring configurations prior to 11.0 are restored as tagged monitor ports only.
The traffic egressing the monitor port can either be tagged or untagged. If the mirroring is enabled as
tagged on the monitor port of the BlackDiamond 10K switch, all traffic egressing the monitor port is
tagged. In this case, even if some untagged ports send mirrored traffic to the monitor port, that traffic
also egresses the monitor port tagged. And, if mirroring is enabled as untagged on the monitor port, all
traffic egressing the monitor port is untagged, including mirrored tagged packets.
When you upgrade to 11.0, all restored mirroring configurations are tagged monitor ports only.
Example
The following example selects slot 3, port 4 as the mirror, or monitor, port on the BlackDiamond 8810
switch:
enable mirroring to port 3:4
The following example selects slot 1, port 3 as the tagged mirror, or monitor, port on the BlackDiamond
10K switch:
enable mirroring to port 1:3 tagged
History
This command was first available in ExtremeWare XOS 10.1.
Beginning with ExtremeWare XOS 11.0, you must configure the monitor port as tagged or untagged on
the BlackDiamond 10K switch.
Platform Availability
This command is available on all platforms.
